- UFC president Dana White stopped by ESPN's "SportsCenter" on Wednesday and revealed the co-main event for UFC 173 in May has been signed. The bout will feature Daniel Cormier against Dan Henderson from Las Vegas.

Cormier (14-0) and Henderson (30-11) are both former U.S. Olympic wrestlers, each of whom are coming off victories inside the Octagon. "DC" stopped Patrick Cummins in his 205-pound debut, while Henderson earned a second victory over Mauricio "Shogun" Rua via knockout.

White confirmed that the winner will move one step closer to a shot at the UFC title. Current champion Jon Jones defends this Saturday against Glover Teixeira at UFC 172, while Alexander Gustafsson is set to face the winner of that fight later this year.

The card will also feature UFC bantamweight champion Renan Barao against T.J. Dillashaw and welterweights Robbie Lawler and Jake Ellenberger. It is set for May 31.

- UFC bantamweight champion Ronda Rousey's "call-out" of Cris Cyborg has provoked outrage from an MMA clothing line. Americana is offering a $5,000 reward to the first fighter that can knock Rousey out.

The clothing line felt Rousey was wrong to refer to Cyborg as an "it" during a recent interview, as she insists the amount of steroids and drugs Cyborg has taken has changed her body. Cyborg's only failed drug test came from an anabolic steroid that she claims was used for weight-cut and not muscle mass.

The Americana MMA Facebook page also added a post regarding the matter, saying, "Matt Mitrione calls Fallon Fox a freak; Matt Brown says that WMMA would be more exciting if women fought topless; both fighters are reprimanded. Ronda Rousey states that Cyborg is not a woman but more of an 'it,' and nothing happens."

Americana will give $5k to the first fighter that knocks out Ronda Rousey.

- As part of her desire to continue getting pro wrestling fans excited about female MMA, Ronda Rousey has released another video of her competing inside the squared circle. Rousey and her MMA teammates, Shayna Baszler, Marina Shafir and Jessamyn Duke show off their skills in the video above.

The group refers to themselves as the "Four Horsewomen" and have released two previous videos showcasing what they can do outside of the Octagon. Duke will actually be in action this weekend at UFC 172 when she meets Bethe Correia on the FOX Sports 1 televised prelims.

Rousey's next fight is set for UFC 175 in July, as she defends her title against Alexis Davis in the co-main event. Baszler is signed to the UFC, but is currently injured, while Shafir only recently made her pro MMA debut.
